Greek number prefixes are employed in the naming of molecular (covalent) substances.

Greek number prefixes are employed in the naming of molecular (covalent) substances. Prefixes are always combined in order of size (left-to-right in the table below). For instance, "heptadecatetracta" (7 + 10 + 400) would be the prefix for the number 417.

We utilise prefixes (mono-, di-, tri-, etc.) at the beginning of each element in molecular compounds to denote the element's subscript, but we only use the prefix mono- for the compound's second element.

approximation underestimates the exact area by 1/3. We can compare this approximation to the exact area under the parabola y = x^2 on the unit interval, which is known to be 1/3. The difference between the approximation and the exact area will be determined.

The approximation derived from the given ratios in problem 1 suggests that 2/3 of the children play a musical instrument. Comparing this approximation to the exact area under the parabola y = x^2 on the unit interval, we find that the exact area is 1/3.
The difference between the approximation and the exact area can be calculated by subtracting the approximation (2/3) from the exact area (1/3). Performing the subtraction, we get:
1/3 - 2/3 = -1/3.
The result is -1/3, indicating that the approximation from problem 1 differs from the exact area by -1/3. In other words, the approximation underestimates the exact area by 1/3.

Lou and Mira can rescind the contract to sell an MP3 player to Mira for $50 if both parties agree to the terms of rescission and sign a written agreement.

Rescission of a contract refers to an equitable remedy granted by the courts or given as a contractual right to one party to terminate a contract. This remedy returns the parties to their former positions before the contract's execution, which requires that both parties to a contract return whatever benefits they had received during the transaction.

In Lou and Mira's scenario, the rescission of their contract to sell an MP3 player to Mira for $50 can be possible if the parties reach an agreement to rescind the contract in writing. The following steps should be taken to rescind the contract:

1. The parties should agree to rescind the contract: For a rescission to be effective, both parties must consent to rescind the contract. This is possible if both parties agree to the terms of rescission and sign a written agreement. The agreement must state the date of rescission, the reason for the rescission, and the terms of the agreement.

2. Restitution: Restitution refers to the return of the subject matter of the contract. Since it is an MP3 player, Lou must return the MP3 player to Mira. In turn, Mira must also return the $50 to Lou. This will effectively end the contract, and the parties can go their separate ways.

3. Cancellation of any obligations: The parties must agree to cancel any obligation that arose from the contract. In this case, no obligations may arise from the rescission of the contract, so no further action is required.

4. Record keeping: It is crucial to keep a record of the rescission agreement. This record will serve as evidence of the rescission if any legal issues arise. It should include the date of rescission, the reasons for rescission, and the terms of the agreement. The parties must keep a copy of the document for their records.

In conclusion, Lou and Mira can rescind the contract to sell an MP3 player to Mira for $50 if both parties agree to the terms of rescission and sign a written agreement. The agreement must include the date of rescission, the reason for rescission, and the terms of the agreement.

Answer:

$27.5

Step-by-step explanation:

Let

x = pound over weight limit

Airline 1 = 20 + 10x

Airline 2 = 5 + 30x

Equate the fees

20 + 10x = 5 + 30x

20 - 5 = 30x - 10x

15 = 20x

x = 15/20

x = 0.75 pounds

How large was each airline's fee?

Airline 1 = 20 + 10x

= 20 + 10(0.75)

= 20 + 7.5

= $27.5

Airline 2 = 5 + 30x

= 5 + 30(0.75)

= 5 + 22.5

= $27.5

Mean of country A is $29600 and median $29000. Mean of country B is $49800 and median is $29000. Country B has greater income inequality. So option B is the correct answer.

Mean of incomes in country A = (9000+ 21000+ 29000 + 39000+ 50000)/5   =  $29600

Median income of country A = (5+1)/2 th term = 3rd term = $29000

Mean to median ratio = 29600/ 26000= 1.02

Mean income of country B = ( 9000+ 21000+ 29000+ 39000+ 151000)/5 = $ 49800

Median income = (n+1)/2 th term = (5+1)/2 = 3rd term = 29000

Mean to median ratio of country B = 49800/29000 = 1.71

Since mean and median are closer to each other, standard deviation is less. The mean to median ratio is greater for country B. So country B has greater income inequality.

If the income inequality has been increasing, then the mean-median ratio will increase, due to the extreme values, mean will increase. So option B is the correct answer.

Answer:

Volume = 261.8 cm³

Surface area = 254.2 cm²

Step-by-step explanation:

To calculate the volume of the cone, we have to use the following formula:

\(\boxed{V = \frac{1}{3} \pi r^2 h}\),

where:

V ⇒ volume

r ⇒ radius = 5 cm

h ⇒ height = 10 cm

Using the above formula and the provided measures, we get:

V = \(\frac{1}{3}\) × π × (5)² × 10

    = \(\frac{1}{3}\) × π × 25 × 10

      = 261.8 cm³

In order to calculate the surface area of the cone, we have to use the following formula:

\(\boxed{SA = \pi r^2 + \pi r l}\)

where:

SA ⇒ surface area

r ⇒ radius = 5 cm

l ⇒ slant length = \(\sqrt{r^2+h^2}\) = \(\sqrt{5^2+10^2}\) = 5√5 cm

Using the formula,

SA = π × (5)² + π × 5 × 5√5

     = π × 25 + π × 25√5

     = 254.2 cm²

a) The probability that the bank is empty is approximately 0.0026.

b) the average time the customer spends waiting to be called is approximately -0.25 c) hours the average number of customers in the bank is -1.5 d) the average number of customers waiting to be served is approximately 9.

To answer these questions, we can use the M/M/4 queuing model, where the arrival rate follows a Poisson distribution and the service time follows an exponential distribution. In this case, we have four bank tellers, so the system is an M/M/4 queuing model.

Given information:

Arrival rate (λ) = 12 customers per hour

Service rate (μ) = 1 customer every 15 minutes (or 4 customers per hour)

(a) To calculate the probability that the bank is empty, we need to find the probability of having zero customers in the system. In an M/M/4 queuing model, the probability of having zero customers is given by:

P = (1 - ρ) / (1 + 4ρ + 10ρ² + 20ρ³)

where ρ is the traffic intensity, calculated as ρ = λ / (4 * μ).

ρ = (12 customers/hour) / (4 customers/hour/teller) = 3

Substituting ρ = 3 into the formula, we have:

P = (1 - 3) / (1 + 4 * 3 + 10 * 3² + 20 * 3³) ≈ 0.0026

Therefore, the probability that the bank is empty is approximately 0.0026.

(b) The average time the customer spends waiting to be called is given by Little's Law, which states that the average number of customers in the system (L) is equal to the arrival rate (λ) multiplied by the average time a customer spends in the system (W). In this case, we want to find W.

L = λ * W

W = L / λ

Since the average number of customers in the system (L) is given by L = ρ / (1 - ρ), we can substitute this into the equation to find W:

W = L / λ = (ρ / (1 - ρ)) / λ

W = (3 / (1 - 3)) / 12 ≈ -0.25

Therefore, the average time the customer spends waiting to be called is approximately -0.25 hours, which is not a meaningful result. It seems there might be an error in the given data.

(c) The average number of customers in the bank (L) can be calculated as:

L = ρ / (1 - ρ) = 3 / (1 - 3) = -1.5

Therefore, the average number of customers in the bank is -1.5, which is not a meaningful result. It further suggests an error in the given data.

(d) The average number of customers waiting to be served can be calculated as:

\(L_q\) = (ρ² / (1 - ρ)) * (4 - ρ)

Substituting ρ = 3, we have:

\(L_q\\\) = (3² / (1 - 3)) * (4 - 3) ≈ 9

Therefore, the average number of customers waiting to be served is approximately 9.

There are 2375 square feet of grass on Lois's lot.

To calculate the area of the grass on the lot, first calculate the area of the entire trapezoidal lot and then subtract the area of the house and driveway.

Let's call the trapezoid's top base "a," its bottom base "b," and its height "h." Then we can apply the formula for trapezium area, which is:

A = (a+b)/2 * h

We can see from the diagram:

a = 80 ft

h = 75 ft

b = 120 ft - 25 ft (driveway length) - 25 ft (house length) = 70 ft

As a result, the total area of the property is:

A lot = (80 ft + 70 ft)/2 * 75 ft = 5250 sq ft

According to the diagram, the width is 25 feet and the length is 35 feet. As a result, the house's area is as follows:

A house = 25 ft * 35 ft = 875 sq ft

A driveway = 25 ft * 80 ft = 2000 sq ft

As a result, the area of grass on the lot is:

A grass = A lot - A house - A driveway = 5250 sq ft - 875 sq ft - 2000 sq ft = 2375 sq ft

As a result, there are 2375 square feet of grass on the lot.

The RAS model suggests that individuals have varying levels of political knowledge and are exposed to different sources of information. Those who are more likely to receive the message are individuals who are politically interested and engaged, while those who are more likely to accept the message are individuals who have limited political knowledge and are less critical of the information presented to them.

Step-by-step explanation:

I guess the simplification is aiming to bring both terms into one fraction with the same denominator (bottom part).

and I assume this expressing is actually

(5/4)×a - (2/3)×b

or

simply

5a/4 - 2b/3

if that is so, then :

the common denominator is the smallest (or lowest) common multiple of 4 and 3.

and that is here simply 12 (there is no smaller number that can both be divided by 4 and by 3 without remainder).

so, we need to bring both fractions to .../12 and then combine them.

how do I do that ?

I multiply each fraction with another fraction that has the overall value 1 (to and bottom numbers are equal) but changes the denominator to 12.

that way I don't change the value of the original fraction, but I only change is appearance.

so, what do I need to multiply 4 with to get 12 ?

right, 3.

that gives us

5a/4 × 3/3 = 3×5a/(4×3) = 15a/12

and what do I need to multiply 3 with to get 12 ?

right, 4.

2b/3 × 4/4 = 4×2b/(3×4) = 8b/12

alright !

now we write the original expression using its new looks :

15a/12 - 8b/12

and that is

(15a - 8b)/12

alternative :

what if the typing was actually correct, and we are dealing with

5/(4a) - 2/(3b)

we still need to bring both fractions to the same denominator.

we know the smallest common multiple of 4 and 3 is 12.

and the smallest common multiple of a and b is ... ab.

so, we need to bring everything the fractions of the form .../(12ab)

again, the same trick, we multiply with fractions of value 1 (to and bottom are equal) but that cover the denominator to the desired common denominator.

what do I need to multiply 4a with to get 12ab ?

well, 3b

so, we get

5/(4a) × 3b/(3b) = 5×3b / (4×3ab) = 15b/(12ab)

and what do we need to multiply 3b with to get 12ab ?

well, 4a.

2/(3b) × 4a/(4a) = 2×4a / (3×4ba) = 8a/12ba = 8a/(12ab)

and together this gives us

(15b - 8a)/(12ab)
